A ??Good? quality may result in no QualityField attribute being returned.
If ??Bad?, or ??Uncertain? then a QualityField attribute will be returned. The server will NOT return a value if the quality is Bad, except as described in OPC specification.
The server is required to return a ??reasonable? value when the quality is uncertain. Clients may specify a QualityField when performing a Write.
